Rumble Go builds upon the legacy of the original Rumble Jar by adapting our award-winning filters so they fit into containers that are a little more portable than a Mason jar. Rumble Jar is made for your home, while Rumble Go is made for the road.

Now it's simple to make professional-grade cold brew coffee anywhere you go. Just take some coarsely-ground coffee beans, add some lukewarm water, and give it a quick "rumble". Total prep time takes less than a minute, and by the morning you'll have delicious cold brew coffee. See how easy it is to brew a batch

Stainless steel insulated wide-mouth bottle (34oz). This highly durable bottle is built out of 18/8 stainless steel (the same kind of steel we use in our filters). Its powder-coated exterior is soft to the touch, and it features a flip lid that's surpringly leak-proof. Our early fans might remember this bottle's smaller cousin from our Kickstarter campaign in 2018. That bottle ended up getting such high marks that we decided it was time to bring it back, but this time in the larger 34oz form!

Stainless steel filter. Built out of dent-resistant 18/8 stainless steel, this surprisingly sturdy filter will have you saying goodbye to those flimsy mesh filters, those plastic parts, or those disposable paper filters, since all that stuff was designed for brewing hot coffee anyway. Experts agree that coarse grounds make the best cold brew, and 200 microns is the ideal hole size for perfectly filtering coarse ground coffee beans. A bigger hole size would yield too much sediment, while a smaller hole size would yield weak-tasting coffee. 200 microns is "just right". Our filter also features three notches on the side. Those notches help you figure out the right amount of grounds to use, since precise measurements become impractical when you're away from home. see it up close

Universal, extendable base and cap. Designed using BPA-free, FDA-approved food grade silicone, the base features 11 different height adjustments that extend the filter by up to 1.5" so it can fit into a wide range of popular 16-32oz wide-mouth bottles (plus our very own 34oz bottle). The base and the cap work together to keep the grounds secured inside the filter while also acting as shock-absorbers to prevent rattling. The cap is designed to allow the filter to nest fully inside a bottle, so the filter never interferes with your bottle's airtight, leakproof seal. see it up close

Rumble Go's flexible design allows it to extend and fit a wide variety of popular wide mouth water bottles
